CLUTCH.

SPECIFICATION forming part of Letters Patent No. 765,788, dated July 26,1904.

Application filed September 14:, 1903. Serial Nx 178,138. (No model.) I

To all LU/b07721 it may concern.-

Be it known that I, CHRIsTIAN PEDERSEN, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and'usefulImprovement in Clutches, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a side elevation, partly in section. Fig. 2 is a plan view,chiefly in section; and Fig. 3 is a detail front elevation, partly insection.

This invention relates to improvements in clutches, the object being toprovide a powerful clutch of simple construction and convenientoperation.

To these ends and also to improve gener- I ally upon devices of thecharacter indicated annular groove or recess 5, in which is received aleather or other packing 6, which projects slightly beyond what may betermed the inner face of said second clutch member. hen-said clutchmembers are forced into engagement with each other, the face 3 of theclutch member 2 engages said projecting packing 6, and the clutchmembers are thus so engaged with each other that they are compelled torotate together. The disk 4 upon its side opposite that upon which theclutch member 2 is located is adapted to bear against some suitableabutment (such as the machineframe 7, in which the shaft 1 is mounted)in order to prevent movement of said disk 4 away from said disk 2.

At what may be termed the outer side of the .disk 2 is a frame 8, whichhas a plate 9, adapted to be secured to the frame of the machine or anyother suitable support, said frame 8 having a slot 10. Through the wall11 of the frame intermediate said slot and what may be termed the outerface of the disk 2 is an opening or seat 12, through which a pin 13 ismovable, said pin bearing against the outer face of the disk 2 (or aplug 1 1, driven in the axial opening through said disk) at the centerof rotation of the same. This pin is preferably rounded at both ends.

Mounted upon the pivot-pin 15, which extends across the before-mentionedslot 10, is a bell-crank lever 16, which can be conveniently providedwith a treadle 17 upon its substantially horizontal arm. Thesubstantially vertical arm of the lever is enlarged and formed into ahead 18, which has a cam or inclined face 19 adjacent the end of thesaid pin 13. A spring 20, suitably secured to the frame 8, bears at oneend against the under side of the treadle, and thus serves to hold thelever 16 in what may be termed inoperative position.

Connection is made between the disk 2 and the source of power andbetween the disk A and the mechanism to be driven, so that the disk 2constantly operates. When the lever 16 is in inoperative position, itshead 18 is clear of the pin 13 and the disk 2 is free to move away fromthe disk 4. When, however, the treadle 17 is depressed, the cam-head 18of the lever engages the pin 13, forces the same against the disk 2, (orthe plug 1 1, which is practically a part of said disk,) and thus forcessaid disk 2 into clutching engagement with the disk 1, whereupon thedisk 4 is rotated.

For convenience of construction the axial opening 21 is bored entirelythrough the hub of the disk 2, and the plug 14: is then driven into whatmay be termed the outer end of said opening in order to form a bearingfor the pin 13.

I am aware that minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and hers and adapted to engage saidclutch menu her, said pm belng in the path of movement ofsaid lever;substantially as described.

In testimony whereof I hereunto afiiX my 5 described without in theleast de 'iarting from signature, in the presence of two witnesses,

the nature and principle of my invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is

In a clutch, cooperating clutch members, a frame having means forattaching the same to a support and having a slot formed therein, alever pivoted to said frame and operating T0 in said slot, and a pinsupported in the wall of said frame adjacent one of said clutch memthis31st day of August, 1903.
